操作特性 

„

 

供電後G-RAYS 2會自行啟動並自我測試完成後,G-RAYS 2之
Bluetooth LED (藍色)與GPS LED (紅色)會亮起表示藍芽與GPS
啟動,同時GPS進入自動定位模式隨即開始接收衛星訊號,並自
動進行定位追蹤。正常在天空無遮蔽狀況下,定位約需34秒
鐘。(如果內部記憶中的位置推算資料仍有效,則只需3~33秒
鐘。) 定位後,包含有效的位置資訊、速度、時間的NMEA 0183
資料即由輸出端輸出。 

„

 

當首次使用本產品時,將GPS 接收器放置於衛星訊號良好的環
境中,大約13 分鐘內(理論值12.5分鐘)即可收到或更新完整
的星歷資料(ALMANAC)。若有任何收訊不良情形,請先參考疑
難排解,通常問題可以迎刃而解。 

„

 

G-RAYS 2利用內部儲存的初始資料,包含前次儲存的位置、日
期/時間及衛星軌道資料,推算出目前天空所在的衛星分佈並加
以追蹤鎖定,以達到最佳的接收效果。如果內部儲存的初始化
資料不正確,或衛星軌道資料已被清除,則需要較長的時間才
能定位。但當下列狀況出現時,G-RAYS 2會採用較長時間的冷
開機模式:

G-RAYS 2定位後,便經由輸出介面,開始傳送有效的導航資
料。這些資料如下:
